Title: Gear pump
Inventor: SHIDAHARA YASUSHI
IPC: F04C2/08
Filed: 1997-06-23
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of vibration and noises due to containment phenomenon of a pump, prevent wear of a part to support the spindle of a gear and provide excellent durability, and prevent lowering of pump efficiency during a high pressure. SOLUTION: In this gear pump, a flow passage 80 to cause a flow of working fluid from a closed region to a support hole is formed in a side plate 12 to partition a gear chamber. The flow passage 80 is opened on the closed region side and to a recessed part 81. The recessed part 81 avoids clearance grooves 63 and 64 for preventing the occurrence of containment and avoids an engagement working line L of engagement of two gears. Lowering of pump efficiency during high pressure due to communication between a discharge chamber and a suction chamber is prevented from occurring. The recessed part 81 is arranged close to a drive gear and communication of a discharge chamber and a flow passage 80 with each other is prevented from occurring.

Title: Cleaning device of blast furnace gas
Inventor: ONO YOSHIYUKI
IPC: B01D50/00
Filed: 1982-09-24
Abstract: PURPOSE:To treat directly a blast furnace gas, and to remove dust to a target dust content at a stroke, and to reduce an installing space, by combining a dust catcher and a single cylinder type bag filter provided with plural dust chambers. CONSTITUTION:A blast furnace gas containing dust sent from the top of a blast furnace is blown out from a bottom opening of an introducing pipe 11, and coarse grained dust falls by gravity to the inside of a hopper 10a without changing its flow direction. Most of fine grained dust ascends while entraining a gas flow and transmits through a group of filter clothes 15 of dust removing chambers from their lower sides. In this transmission, the fine grained dust is caught by the filter cloth 15, and the clean gas passes through filter valves 19 and is sent from a clean gas discharging pipe 18 to a turbine for recovering a pressure in the furnace top, etc. At that time, for only one of the dust chambers, the valve 19 is closed and a backwashing valve 21 is opened to blow the clean gas into it from the upper side by a backwashing fan 20. The dust sticking to the filter cloth is removed and is made to fall into the hopper 10a.
